Application led August 2, 1915, Serial No. 43,074. Renewed July 14, 1917. Serial No. 180,681.

To all whom t may concern:

Be it known that I, PHILIP J. HAAS, a citizen of the United States, residing at Omaha, county of Douglas, and State of Nebraska, have invented new and useful improvements in later-Heaters, of Which the following is a specification.

My invention relates to improvements in Water heaters, and more especially to stock tank heaters.

One of the objects of my invention is 'the provision of means for draining the Water coil to prevent freezing thereof without draining the tank Water through the coil.

Another objectv of the invention is the provision of a compensation coil outlet pipe to maintain the discharge opening thereof below the tank Water surface With a constant'interval between it and the Water surface as it rises and falls in the tank from replenishment or consumption thereof.

A further `object of the invention is the provision of lengthy Water coil intake and outlet pipes to conduct the cold Water from a point remote from the heater body, heat it in the coil and discharge the Warm Water at apoint remote from the heater body.

A still further object of the invention is the provision of a compensation water coil outlet pipe which rises and falls With the tank Water and enables the rapid continuation of the Water circulation between the tank and the heater coil after the Water level in the tank has sunk to a plane below the top of the heater coil, or below the point of water exit from the heater coil.

Further objects of my invention will be mentioned and described in the specification following.

On the drawings Figure 1 is a vievv in elevation, partially in section, through a tank and heater embodying my improvements; Fig. 2 is a cross section through the heater in different planes showing the inlet, outlet and drain pipe arrangement; Fig. 3 is a side elevation of the outlet pipe adjacent the heater; Fig. 4C is a. section through the heater cover and its parts; and Fig. 5 is a view of the pivotal connection of the compensation outlet pipe.

Similar numerals refer to similar parts throughout the several views on the drawn the drawings the numeral 1 designates a Water tank of metalor .other suitable material, within which. 1s disposed the heater 2 adapted to be spaced from the Sides of the tank. rlhe numeral 3 indicates a heater cover, or top, of metal, provided with a fuel insertion door t, the cold air draft damper 5, the smoke stack G and the vent opening 7, the Vcover 3 being secured to the heater body 1 in any suitable manner. The numeral 8 designates a Water heating coil arranged Within the heater 1 and above the lire grate 9 andsupported therein by the heater body at the points of Water entry and exit.

rllhe numeral 10 designates an ashpit provided With the opening 11 formed in the heater body adjacent the bottom thereof.` The numeral 12 designates a channeled ashpit connection placing the ashpit 10 in communication ivith the tank exterior.

rThe numeral 13 designates an annular member rigidly secured tothe heater body 1 and around the opening 11 and int-o which the channeled member 12 is screw threaded. Numerals 14C and 15, respectively, designate inner and outer sealing nuts, screw threaded on member 12 and screwed tightly against the inner and outer surfaces of the tank Wall 1 to seal against Water leakage around member 12 at the point of tank Wall penetration thereby.

The numeral 16 designates a cylindrical and hollow damper member slidably disposed Within the member 12 and provided with draft openings 17, 17 and aysuitable handle for operation thereof. The coil 8 has its bottom coil memberconnected With a water inlet member 18 through an opening formed in the side of the heater 2, and its top coil member connected With an outlet pipe member 20. rlhe numeral 19 designates a drain pipe connected With the three Way valve 227 one of the members of the inlet pipe 18, extending laterally therefrom to the tank exterior through the opening 21. The numeral 23 designates a valve rod and handle for actuating the valve 22. The riser member 24, also a member of the inlet pipe 18, connects the valve 22 with the lower coil member of the heater coil 8. The outer member of the Water intake pipe 18 is arranged adjacent the tank bottom and has its open intake end extended to a point adjacent the tank wall and remote from the heater body 2 to intake the cold Water from a point remote from the heater body.

The numeral 20 designates a compensation coil outlet pipe ,member provided with an elbow 28 loosely screw threaded into the flange of the two way valve 29 at 30 to permit of free movement of the Y elbow threads in said flange threads at 30. The pipe member 2O is provided also with a float 26 secured thereto by straps 27, 27 and above and adjacent they discharge opening end thereof to keep the discharge end thereof slightly/'submerged at all times while there is a reasonable amountof `water in the tank l. Being pivoted at 30, the elbow 28'- and member 2O rise-and fall with the water. level in thetank, as itis replenished or consumed,

Vand the discharge end ofl pipe membery 20,

being, located. at a point remote from the beaten always delivers warm water at a point distant therefrom and adjacent the tank.: wall.

The numeral 31 designates an air relief. pipe connected with the outlet pipe 20 which is provided with a pet-cock 32. The valve 29.` is actuatedby a valve rod and lever 83.

`To drain the coil 8 valve 29 is closed to preventv the tank water from entering through pipe 20, the three-way valve 22` is closed against the intake pipe 18, and the pet-cock 32 is opened to admit air to the interior of pipe 20. Thereupon all water in the coil 8 will.A drain` through pipe 19 to the tank exterior. By leavingl valve- 29 open to pipe member 2O,y opening the pet-cock S2" andl closing valve 22 against pipe 18 a cont-inuousilow of warm water may be had at the discharge end ot drain pipe 19 even after the tank water level has fallen below thel plane of the coil top, for thereafter it is siphoned-Y from the tank.

Nhen in ordinary use the water freely circulates from the tank to the coil and back again to the tank, and thisvcirculation is maintained even after the water level in the tank 1 has fallenv below the plane otA the coilv top, for the dischargeA opening of outlet member 20` is always submerged and maintained jilst beneath the tank water surface by the iioat 26.

1. In a water heater, the combination with a water tank and a water heater within the tank, said heater being provided interiorly with a water coil connected with water coil inlet and outlet members arranged within the water tank, of means for draining said water coil said meanscomprising a valve in said outlet member, air inlet means connected with said water outlet member, a valve in said water inlet member, and. a drain member connected with said inlet member valve and leading to the water tank exterior.

2. Inl a water heater, the combination with a water tank and. a. water heater within the tank, said heater being provided interiorly with a water coil connected with water coil inlet and outlet members arranged within the water tank and in communication with the water therein, ot means for draining said water coil, said means comprising a valve in said coil outlet member adapted te cut olf comn'iunication between the tank interior and the coil, air inlet means intermediate saidy valve and the coil and connected with said outlet member, a valve in said inlet member adapted to cut oit communication between the tank interior and the coil, and a drain pipe connected with said inlet member `valve and adapted to be placed in conminnication with the coil by said valve, said drain pipe leading to the exterior of the water tank.

In witness whereof I have hereunto aiiixed my signature in the presence of two witnesses.

PHILIP J. IIAAS.
